Estimation of coherent demand systems with many binding non-negativity constraints

Pitt, Mark Martin; Millimet, Daniel L. - 1999

Two econometric issues arise in the estimation of complete systems of producer or consumer demands when many non-negativity constraints are binding for a large share of observations, as frequently occurs with micro-level data. The first is computational. The econometric model is essentially an...
